- Backbones of Brazilian Internet:
- Research backbone:
A backbone dedicated to universities and research centers is maintained by Rede Nacional de Ensino e Pesquisa (National Network of Teaching and Research), more commonly
referred to as RNP; visit the RNP website in English (there is also a version in Spanish).
RNP connects all the higher learning centers in Brazil, to promote exchange of educational information.
- Commercial backbones:
The biggest commercial backbone belongs to Embratel; this company used to be a State owned monopolistic with complete control over the long distance and international
calls in Brazil, hence the large network. Embratel was privatized in 1998, bought by American based MCI; the network grew much, keeping the company still as the largest
long distance carrier in Brazil. Take a look at the topology of Embratel network.
Embratel has a presence in all major Brazilian cities, multiple optical links to USA and one to Europe; this makes the company the largest router of internet packets in
Brazil.
Telemar, which is today the largest phone company in Brazil, has a fast growing backbone structure. The company used to have legal geographical limits of actuation; knowing
that the limits had a set date to finish, Telemar made investments to be able to be a player in internet business; click to get a PDF document with Telemar backbone structure (PDF).
Other companies with backbones infra-structures are GlobalOne and IBM; their networks, however, are geographically limited and cater mostly for private corporation routing.
- The SERPRO network:
Another structure worth mentioning is the SERPRO's one. This state owned company is responsible for the communication among almost all government agencies; some agencies,
like the Tax Agency, handle massive amounts of data, and SERPRO does a good job.
